Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production, specifically to a gluing device for corrugated paper production. Background Technology

[0002] Corrugated paper is a composite paperboard made of at least one layer of corrugated core paper and one or more layers of flat paperboard (linerboard). It is lightweight, strong, and provides good cushioning. Its corrugated structure effectively disperses external forces, providing excellent compression and shock resistance, and is widely used in the packaging industry. Corrugated paper is low-cost, recyclable, and combines environmental friendliness with economic efficiency, making it an ideal material for making cartons, liners, display racks, etc., and it is widely used in logistics, electronics, food, and other industries.

[0003] For example, patent announcement number CN 217017179 U discloses a gluing device for corrugated paper production, including a gluing machine. The gluing machine has a second support inside. A first limiting block and a second limiting block are welded to the lower ends of the outer walls on both sides of the second support, respectively. A fourth bevel gear is movably connected to the first limiting block. The fourth bevel gear meshes with a third bevel gear. The third bevel gear is connected to one end of a transmission roller. Both the fourth bevel gear and the first limiting block are penetrated by a first limiting rod. This invention, by starting a motor, drives the first limiting rod to rotate. The third limiting block limits the fourth bevel gear, allowing it to rotate with the rotation of the first limiting rod. This causes the third bevel gear, which meshes with the fourth bevel gear, to rotate, thus rotating the transmission roller. Simultaneously, this drives the second bevel gear to rotate, causing the first bevel gear, which meshes with the second bevel gear, to rotate, thus rotating the glue roller. The glue roller and the transmission roller can rotate simultaneously, driving the corrugated paper for transmission and resulting in more uniform gluing.

[0004] However, the above-mentioned technology does not have a cleaning mechanism at the front end of the glue coating machine. After the corrugated board is produced, residual impurities and dust on the surface will affect the glue coating of the corrugated board. Therefore, the market urgently needs to develop a glue coating device for corrugated paper production to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a gluing device for corrugated paper production, so as to solve the problem mentioned in the background art that the lack of a cleaning mechanism at the front end of the gluing machine will cause residual impurities and dust on the surface of the corrugated board after production, which will affect the gluing of the corrugated board.

[0010] Preferably, a driving device is fixedly connected to the front end of the rectangular slider, and a driving motor is fixedly installed inside the driving device. The front end of the rotating shaft extends into the driving device and is connected to the output end of the driving motor through a coupling.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a gluing device for corrugated paper production, comprising a conveyor belt 1, a gluing machine 101 fixedly mounted on one side of the upper end of the conveyor belt 1, and a second C-shaped fixing frame 3 fixedly connected to the other side of the upper end of the conveyor belt 1. The second C-shaped fixing frame 3 has strip-shaped grooves 301 at the center of both its front and rear end faces. Rectangular sliders 4 are disposed inside each of the two strip-shaped grooves 301. A cleaning roller 402 is rotatably connected to the inner side of the second C-shaped fixing frame 3 and between the two rectangular sliders 4. The front and rear ends of the two rectangular sliders 4 extend out of the front and rear ends of the strip-shaped grooves 301, respectively. Rectangular limiting strips 401 are fixedly connected to both sides of the rectangular sliders 4 and to the front and rear ends of the strip-shaped grooves 301. The cleaning roller 4... A rotating shaft 403 is fixedly connected to the middle of the 02. The front and rear ends of the rotating shaft 403 extend out to the front and rear ends of the cleaning roller 402 and are respectively inserted into the interior of two rectangular sliders 4 for rotational connection. The front end of the front rectangular slider 4 is fixedly connected to a driving device 5. A driving motor 501 is fixedly installed inside the driving device 5. The front end of the rotating shaft 403 extends into the interior of the driving device 5 and is connected to the output end of the driving motor 501 through a coupling. The conveyor belt 1 conveys the corrugated paper, so that the conveyor belt 1 passes the lower end of the cleaning roller 402 first. The driving motor 501 drives the rotating shaft 403 to rotate, so that the rotating shaft 403 drives the cleaning roller 402 to rotate and clean the upper end of the corrugated paper, so that the residual impurities and dust are removed.

[0024] Furthermore, a first C-shaped fixing frame 2 is fixedly connected to the middle of the upper end of the conveyor belt 1. A cross-flow fan 202 is fixedly connected to the upper end of the first C-shaped fixing frame 2. A folded rectangular air guide duct 201 is fixedly connected to the upper inner side of the first C-shaped fixing frame 2. The upper end of the folded rectangular air guide duct 201 passes through the upper end of the first C-shaped fixing frame 2 and is fixedly connected to the lower air outlet of the cross-flow fan 202. After being cleaned by the cleaning roller 402, the corrugated paper continues to be conveyed by the conveyor belt 1 through the lower end of the folded rectangular air guide duct 201. By starting the cross-flow fan 202, air is sent to the upper surface of the corrugated paper through the folded rectangular air guide duct 201 to blow away the dust and impurities remaining on the surface of the corrugated paper, ensuring that the surface of the corrugated paper is clean. Finally, glue is applied by the glue applicator 101.

[0025] Please see Figure 2 and Figure 3 An electrically controlled lifting rod 302 is fixedly connected to the upper middle part of the second C-shaped fixing frame 3. A C-shaped lifting frame 6 is provided on the upper inner side of the second C-shaped fixing frame 3. The lower telescopic end of the electrically controlled lifting rod 302 passes through the second C-shaped fixing frame 3 and is fixedly connected to the upper surface of the C-shaped lifting frame 6. The front and rear ends of the lower end of the C-shaped lifting frame 6 are fixedly connected to the upper surfaces of two rectangular sliders 4 respectively. The C-shaped lifting frame 6 is driven to rise and fall by the electrically controlled lifting rod 302, so that the C-shaped lifting frame 6 drives the two rectangular sliders 4 to rise and fall along the two strip grooves 301 respectively, thereby driving the cleaning roller 402 to rise and fall, so as to adjust the height of the cleaning roller 402 according to the thickness of different corrugated paper.

[0026] Working Principle: During operation, the corrugated paper is conveyed by conveyor belt 1, first passing under the cleaning roller 402. Drive motor 501 rotates the cleaning roller 402 via rotating shaft 403, rolling and cleaning the surface of the corrugated paper to remove residual dust and impurities. Subsequently, the corrugated paper continues to move under the angled rectangular air guide duct 201. The airflow generated by the cross-flow fan 202 blows downwards through the angled rectangular air guide duct 201, further removing surface dust and ensuring a clean adhesive coating surface. The electrically controlled lifting rod 302 adjusts the height of the C-shaped lifting frame 6, causing the rectangular slider 4 to slide up and down along the strip groove 301, thus adapting to corrugated paper of different thicknesses and ensuring the cleaning roller 402 remains in contact with the paper surface. Finally, the cleaned corrugated paper enters the glue coater 101 for uniform glue coating.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
